FOR ALL PI MODDERS

Sat May 03, 2014 11:18 am

Hi there I just got my raspberry pi the other day and installed raspbian wheezy all works well :) I was looking around and it seems some people have added fans to their raspberry pi but most are tiny 5v fans as that's all the pi can handle. SO instead I got and old AMD cpu fan and at 11.1v and made a sepertae power supply unit at 12v 5.0a and ran it from that as the pi cant handled 12v and omg this fan spins fast and works much better than the small 5v fans from ebay. I have overclocked my pi to turbo (1ghz) and with the fan my temps are at 30 degrees amx when running programs :)

I don't know, 30C is still above room temperature :roll:. Sure you don't need one of these? :D

A tiny 5V fan is all that's ever likely to be necessary. There's no harm in having fun with a bigger one though. :D

Pha, rubbish! The lightweight uses aluminium to contact the ICs and transfer heat.If you're going to over do it, really over do it. Nothing less than diamond interface will do.

I've nothing else to add really. It's fun but not necessary. I can understand wanting to do it just for fun though. :)

hi yes it was just intended for fun but I may aswell keep it like that now. With recently getting my pi do you know any projects I could do with it and also for overclocking how would I get it beyond 1ghz turbo therss no more options can I manually change the values for overclcoking

You're unlikely to get 100% stability much above 1GHz no matter how much you cool it. Try installing the Darkplaces Quake engine and leave it running for at least 15 minutes on the clocks you have now before trying to go any higher. You may find that you're already at the limit. We can look at pushing it further after.

The PLL's wont go any higher than 1.2Ghz anyway, so that's the upper limit anyway.

Oh? I've seen reports of people going higher. Were they just bumping the arm_freq in config.txt without any effect? That's a little amusing, since aside from performanc eimprovements, they were reporting instability at a point higher than 1.2GHz. I guess those were just placebo and nocebo effects.

or they were just pushing their pi harder, and so it crashed more often...
